A city setting? Have you guys managed to create a city map that doesn't kill the framerate or is it just to show off the mech?

Now, let me try to guess those loadouts:
From left to right
Two Medium (Pulse?) Lasers, one Small Laser, one SRM4
One Heavy Beam Laser, one Small laser, one LRM10
One RAC 5/10, 3 MGs [BA Killer, yay xD]
One LRM15, one Small Laser, 2 MGs
Or is the thingy on the left shoulder on all variants but the 3 MG one a TAG laser?
